3D layout tool

The LN-150 is a compact, self-leveling, easy-to-setup 3D
layout tool designed for construction applications. Use the
LN-150 in place of traditional methods such as tapes or
other layout tools. Compact, rugged and lightweight, the
LN-150 is ideal for construction layout and as-builts.

Building Information Modeling (BIM)

Maintain coordination throughout your projects. Knowing
what was done before and working from the same design
plan is critical to keep on schedule and avoid costly
collisions. With Topcon BIM solutions, you stay connected
to the same design.
